Background:
Minimally invasive spine surgeries (MISS) are currently used for a wide variety of intradural spinal pathologies. Although MISS techniques have brought great benefits, primary dural closure can prove a challenge due to the narrow corridor of the tubular retractor systems.
Objective:
To present the surgical technique we developed for dural closure using an extracorporeal knot that is simple and reproducible.
Methods:
We describe the use of an extracorporeal knot for primary dural closure in MISS surgeries using standard instrumental. We illustrate this operative technique with figures and its application in a surgical case with images and demonstration video2.
Results:
Using our surgical technique, a watertight dural closure with separated knots was performed without specific instruments.
Conclusion:
The use of extracorporeal knots facilitates primary dural closure in MISS surgeries.
